In news that has to hit the Carol Corps right at their... core, longtime "Captain Marvel" writer Kelly Sue DeConnick announced during a panel yesterday at HeroesCon that she will be leaving the series following the wrap-up of "Secret Wars."

"So hard to go, but it's time," she confirmed via Twitter.

DeConnick's four-year run on "Captain Marvel" has been met with overwhelming positive response, tying the writer to the character in the minds of many fans in that rare way only longtime comic readers fully appreciate. Before her takeover of the series, Captain Carol Danvers was a character who had fought crime under many aliases -- from Ms Marvel to Binary to Warbird -- but under DeConnick's stewardship Danvers earned a promotion to become the House of Ideas' one and only "Captain Marvel." It is this iteration of the character, with no suffix attached to her identity but for her rank, that Marvel will bring to the big screen on November 2, 2018.

The prospect of the pending film and the hype that will undoubtedly surround it forced the writer to reevaluate whether she was prepared to "dig in for three more years or drop the mic," according to a report from The Beat. She opted for the latter.

During her time as "Captain Marvel" writer, DeConnick used her active presence on social media to highlight the way the character's modern costume design became a cosplay sensation, bringing fans of all kinds together in celebration of their love for the classic Marvel character. She dubbed them the "Carol Corp," and even incorporated the concept into the title for the "Secret Wars" event, re-dubbing the series "Captain Marvel and the Carol Corp."

Marvel has not yet announced who it will draft to take over as series writer and de facto commander of the Carol Corps in DeConnick's absence.
